DOM (Drawn Over Mandrel) steel tubing stands out in the metals industry due to its unique manufacturing process and wide range of applications. This tubing, which is known for its high strength and uniformity, plays a critical role in various sectors.
Manufacturing Process of DOM Steel Tubing
Seamless Tubing Formation
Manufacturers start with a solid steel rod known as a billet. They heat this billet and pierce it to create a hollow tube, forming the basis of seamless tubing. This step ensures no seams or welds, attributing to the tubing's exceptional strength.
Drawing Over a Mandrel
The core process involves drawing the tube over a mandrel – a precision tool that shapes and sizes the tubing. This step refines the dimensions and improves surface finish, ensuring uniformity and consistency in the product.
Heat Treatment and Finishing
Post-drawing, the tubing undergoes heat treatment for stress relief and strength enhancement. Finishing processes like cutting to length, straightening, and surface treatment further refine the tubing for its specific applications.
Unique Applications of DOM Steel Tubing
Automotive Industry
In the automotive sector, DOM steel tubing is essential for roll cages, chassis, and suspension components. Its high strength-to-weight ratio contributes to vehicle safety without adding unnecessary weight.
Construction and Infrastructure
DOM tubing's uniform strength and durability make it a popular choice in construction, particularly for structural supports and architectural features.
Precision Instruments
Due to its dimensional accuracy, DOM tubing is ideal for precision instruments, especially in the aerospace and defense industries, where exact specifications are crucial.
Key Advantages and Specifications
